INVENTORWI WILLIAM c. WATKINS Q wmd mmng b Patented July 21, i953 WINDOW STRUCTURE AND GLAZING SEAL THEREFOR William C. Watkins, Los Angeles, Calif.

Application September 24, 1951, Serial No. 248,033

2 Claims.

The present invention relates to a glazing strip, and more particularly to a glazing adapted for use with a multiple pane structure suchas disclosed and claimed in my copending application Serial No. 185,364, filed September 18, 1950, entitled Multiple Pane Window and Door Structure.

Although multiple pane door and window struc-. tures have been in use for a considerable length of time, until the introduction of the invention disclosed in my copending application, these devices had to be fabricated as an integral unit before delivery to the purchaser. As a result, multiple pane structures were only available in stock sizes, and due to the fragile nature thereof, great care was required in handling during shipment,

The usual multiple pane structure has a confined space between adjacent panes in which dry air is captured, and occasionally the glazing of such prefabricated structures breaks in transit due to the differential in pressure between the atmosphere and this confined space. This pressure diflerential will occur due to a change in altitude that could happen during transportation of the units over a mountain range. In addition to this hazard, the glazing of such factory-assembled multiple doors and Windows is frequently broken in transit due to the usual jars and shock to which these structures are subjected.

The door and window structure disclosed and claimed in my copending application, Serial No. 185,364, eliminates the disadvantages of such previously available structures, as well as the need for expensive crating prior to shipment, by providing for glazing after installation;

While the multiple pane structure disclosed in my copending application, Serial No. 185,36 l, has met with distinctsuccess in actual use, it has been found that the actual glazing installation may be facilitated by the use of a new and novel glazing strip of applicants invention, which is the subject matter of the present application. In addition, the new glazing strip of my invention makes possible the assembly of a multiple pane window and door structure embodying a superior seal for the dry air locked between the panes thereof.

A major object of the present invention is to provide a glazing strip that serves to removably hold one or more panes in a fixed position which is adapted to be pivotally moved to exert the proper degree of pressure on the pane or panes by adjustment of the movable screw means operatively associatedwith said glazing strip and name as which it is mounted,

Another object of the invention is to supply means to maintain a pane in a fixed position within a frame which does not require skilled labor for its installation, eliminates the use of putty or other adhesives, and may be accomplished with the minimum use of tools.

A further object of the invention is to provide a glazing strip that may be'fabricated from inexpensive commericallyavailable material, and due to its low cost of production, may be retailed at a suffioiently low price as to encourage Widespread use thereof.

These and other objects and advantages of the invention will become apparent from the following description of a preferred form thereof, and from the drawing illustrating that form in which:

Figure 1 is a perspective View of a multiple pane door and window structure embodying my glazing strip;

Figure 2 is a perspective View of the glazing strip of my invention; i a

Figure 3 is a horizontal cross-secticnal vie of the multiple pane structure taken on the 1. .11:- 3-3 of-Figure 1;

Figure 4 is a fragmentary vertical cross-sectional view of a multiple'pane structure embodying the glazing strip of my invention; 1

-Figure 5 is a fragmentary vertical cross-Ce- V tional View of a supporting strrcture in which a lized to hold the multiple panes P in position in the door and window structure illustrated in Figures 1 and 2.

The structure shown in Figure 1 may be used as a door or 'WlIlClOW, or a combination of both, and includes a fixed panel P and a longitudinally movable panel M. The frame structure includes a sill S and head member H. Member H is supported in the desired position by a fixed jamb J a closing 'jamb C, and an interlocking mullion I. Multiple panes G are separated from one another in panels F and M by a strip of resilient material it. Strip It extends around the edge of each pane G as will be described in detail. Rail l2, forming a part of sill S, extends from the closing jamb C to the fixed jamb J Movable panel M is provided with rollers (not shown) on the bottom edge thereof that engage rail l2, and permit longitudinal movement of the panel between jambs C and J. Sill S preferably terminates in a longitudinally extending member i lon the outer edge thereof that serves as a guide for a movable screen (not shown).

As seen in Figures 1 and 3, fixed jamb J is preferably formed as an integral unit to provide a vertically extending flange 28 from which a member 2! extends forwardly and a second member 22 extends rearwardly. Members 25 and 22 terminate in parallel arms 23 and 2d respectively, that are disposed normal to the members.

Interlocking mullion I comprises a vertically positioned flange 25 positioned in the same vertical plane as flange with a member 26 extending forwardly from flange and terminat on as shown in my copending application, Serial No. 185,364, is formed with an upwardly extending flange 34 in the same vertical plane as flanges 20 and 25. Head member H has a flange (not shown) complementary to flange 34.

The space 35 created by inserting strip ll) between panes G contains dry air, serving as a most effective insulation. The vertical edges of the panes G abut members 2| and 26, with the horizontal edges occupying a like position relative to sill S and head member H. A strip of glazing tape 36 is preferably aflixed to the forward edge of flanges 2e, 25, 34, and the one formed on the head member H. The outer vertical edge portion of the rearwardly positioned pane G is in contact with tape 36 to efiect a seal, preventing the entry of moisture into space 35. Glazing strip 9 is formed or bent from lengths of weather-resistant material such as aluminum or an alloy thereof. Strip 9 is cut into suitable lengths and afiixed to panel F to removably hold panes G in position therein as may be seen in Figures 3 and 4. Strip 9 has a transverse cross section of substantially inverted U-shape which includes a web as that has a leg 4| depending downwardly from the rearward edge thereof, and

a slightly longer leg 42 occupying a like position on the forward edge thereof. A relatively short rearwardly disposed lip 43 is bent or formed from the lower portion of le 42. A number of longitudinally spaced holes 44 are formed in web through which screws 45 may extend downwardly to engage the frame structure on which strip 9 is positioned.

The manner in which the strip 9 effects a tight seal and securely holds one or more panes G in a frame is best seen in Figures 4 and 5. The outer edge portions of the most rearwardly disposed panes G are in contact with glazing tape 35 mounted on flange 34. Strip I0 is preferably of wedge-shaped cross section, and as pressure is applied to the forwardly disposed pane G, the pane contacting strip portions lBa are compressed to form an air-tight seal and prevent entry of moisture within space 35. Pressure is applied to the forwardly dispQ-SQQI pane G y tightening the screws 45, causing the glazing strip 9 to pivot rearwardly in an anti-clockwise direction on lip 43', With such pivotal motion of strip 9 the rearwardly positioned face of leg 4 I or a portion thereof, is forced against the forwardly positioned pane G, which in turn compresses strip portions Illa. In practice it has been found desirable to aflix glazing tape 48 to the exterior portions of the forwardly disposed pane G. It will be particularly noted that legs 4! and 42 are sufliciently separated that they do not contact screws 45 which would limit the pivotal movement of strip 9. The positioning of strips 9 on panel F to hold panes G in position and effect an air-tight seal between the panes and resilient strip l 0 is clearly shown in Figure 3.

In Figure 5 it will be seen that glazing strip 9 may be used to hold a single pane 50 in a suitable frame structure 5!. Glazing tape 52 is preferably affixed to the two edge surfaces of pane 5E disposed between leg 4i and flange 5m, thus assuring a water-tight joint at the junction of pane 5D and flange Sla.

Closing jamb C is an elongate member which has two laterally spaced projecting portions '3! and i2 that engage a stile 73 positioned on one end of movable panel M. An oppositely disposed stile 33 on panel M supports the mullion-engaging member 32. The base portions of stiles l3 and 33 are connected by a horizontal member 15 and the top portions by ahead member (not shown).

Two panes G are supported in panel M separated by strip it to provide an air space 35 identical to panel F. The exterior edge portions of the most rearwardly positioned panes G are forced against flanges Ha, Ma and 15a of stiles 73, M and base member 75 respectively. A downwardly extending flange (not shown) is formed on the head member of panel M in the same vertical plane as flanges 7311., Ma and 15a.

Glazing strips 9 are mounted on the forward exterior portions of stiles 13, I l, and base member 75 to hold the panes G in position in panel M and effect an air-tight space 35 between the panes identical to space 35. One of the glazing strips 9 is also mounted on the head member of panel M to serve the same purpose as the strips disposed on the stiles and base member of the panel.

Thus it will be seen that the glazing strip of my invention permits easy assembly of a multipane structure at the site of installation. A drying element is inserted into spaces 35 and 35' through openings normally covered by removable plates 86 to dry the air confined therein. The dryin element and method of use is fully described in my copending application Serial No. 185,364. In addition to using the glazing strip of the present invention in the fabrication of multipane structures, it will also be apparent that this glazing strip may be effectively employed with single pane structures.

An alternate form of sill S and base 99 for a panel P is shown in Figures 6, 7 and 8. The sill S is fabricated by breaking or forming a longitudinally extending portion thereof into two upwardly extending legs I210 and I0! disposed in side-by-side relationship. The upper extremities of the legs are bent to form a vertically positioned rail section H12 extending the length of sill S. Leg Hill terminates on the lower end in an L-shaped portion :03, while a downwardly sloping sill portion I04 extends forwardly from the lower end of leg ml. The forward edge of includes a horizontal pane-supporting member I06. A member I07 depends'downwardly from the forward edge of member I06 and has a rearwardly extending lip I06 formed on the lower edge thereof. The rearward edge of member I96 is joined to a vertical member that provides an upwardly extending flange I09 and downwardly extending leg IIO. Legs III! and lip I98 cooperate with legs I00 and NH to form :a relatively airtight joint between panel P and sill S.

A number of roller supports IIZ (Figure 7) are longitudinally spaced on base member 99 in the position shown in Figure 6. Each roller support includes a web I I3 from which two laterally spaced legs II4 extend to terminate in flanges H5. The web has an elongateslot H6 formed therein, with two recesses II! in communication therewith and formed in the legs H4. A plate H9 'is provided for each of thesupports which has a cut-out portion in which a grooved roller I20 may be positioned. A shaft IZI is transversely positioned on and aiiixed to the plate to support the roller.

Plate I I9 is mounted on web I I3, with the outer ends of the shaft positioned in recesses I H. The

plate is afiixed to the web by screws I22 which engage bores I23 and I24 formed in the web and.

, plate respectively, as may be seen in Figure 6.

The grooved rollers I20 engage rail I02 and movably support panel P thereon. Panes may be supported on the member I96 in either the manner shown in Figure 4 or that of Figure 5. As may be seen in Figure 6, .a channel I25 may be positioned under sill S for reinforcing purposes. I

Although the glazing strip of my invention is fully capable of achieving the results and providing the advantages hereinbefore described, it

' to such frame, comprising: an elongated web formed with a plurality of bores along its length: a'first leg extending substantially normally from one edge of said web; a second leg extending from the other edge of said web substantially parallel to said first leg, said second leg being longer than said first leg; and a lip formed along the free end of said second leg said strip being adapted to be secured to said frame with the outer surface of said first leg parallel to and abutting the edge of said pane, and the side of within a frame normal to such frame, comprising: an elongated web formed with a plurality of bores along its leng h; a first leg extending substantially normally from one edge of said web; a second leg extending from the other edge of said Web substantially parallel to said first leg, said second leg being longer than said first leg; and a lip formed along the free end of said second leg, said lip being parallel to said web and extending toward said first leg, said glazing strip being adapted'to be secured to said frame with the outer surface of said first leg parallel to and abutting the edge portion of said pane, and the side of said lip remote from said web and parallel to and engaging saidframe by extending said screws through said bores into said frame, the

tightening of said screws eifecting pivotal movement of said glazing strip about said lip toward said pane whereby the outer surface of said first leg may exert pressure against said pane in a direction away from said strip relative'to said frame.
